FOUNTAIN Psa-HOLDER.

SPECIFICATION forming part of Letters Patent No. 298,767, dated May 20,1884:.

Application filed April l1, 1883. (No model.)

To @ZZ whom, t may concern:

Be it known that I, JAMES MoRToN, a citizen of the United States, and aresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in FountainPen-Holders, of which the following is a specification.

The object of my invention is to provide a fountain-pen of a simple andconvenient construction, wherebythe feeding of the ink to the point ofthe pen will be effected in sufficient and even flow by the ordinaryslight bending` of the pen due to the pressure exerted upon its pointwhen writing` and without the necessity of an elastic chamber or otherdevice for producing the feed of the ink by compression of such chamberor its equivalent, and whereby the ink will be at all times preventedfrom leaking out at the upper end of the pen even when the latter isinverted and the cap unscrewed, and whereby, when the writing isfinished, communication between the fountain and the feed-tube may betightly and conveniently shut off to prevent any accidental leakagethrough the feed-tube.

The invention consists in the construction and combination of thevarious parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure l represents a longitudinal centralsection of my improved fountain pen-holder. Fig. 2 is a front view ofthe feed-tube, and Fig. 3 a longitudinal section of the cap by which thepen and feed-tube are covered when not in use.

A is the hollow stem of the holder, which also forms the fountain orreservoir for the ink. This is threaded on the inside a distance down;ward from its upper end to receive the threaded lower end, b, of the capB. The cap B has a hole through its axis, Vwhich hole is enlarged andthreaded at its upper end, b', to receive the threaded shank c of theknob C. In a socket in the said knobCis fastened the upper end of avalve-rod, D, ending with a valvad, which, when the knob C is screweddown far enough, closes a small central opening, c, which opening formsthe communication between thefountain and the feed-tube. A cork,

S, having a central perforation, by which it ts tightly upon the rod D,is inserted and screwed down to fit tightly in the upper end of thereservoir below the cap B, as shown in Fig. l, and does the service of astuffing-box, to prevent any leakage of the ink even if the cap B beremoved or the knob C entirely unscrewed in opening the valve, as whenwriting. From a little below the valve the channel a in the lower end ofthe nipple a of the holder A is enlarged sufficiently to receive afeed-tube, E, having at least. as large a channel in it as the channelc, and toleave a small annular space between the said tube and the innercircumference of the said enlargement or socket to receive and retainthe pen F. This tube E is curved and tapers toward the point e, whichlies in contact with the inner surface of the pen F, and has at the saidpoint e the usual opening, G, for admitting ink to the pen. the frontsurface of the tube E is a little concaved, as shown in Fig. l, so as toleave a small space between it and the inside of the pen for admittingair through asecond small perforation, H. The cross-section of thechannel in the tube E at the hole H is about four times as great in areaas the narrowest portion of the feed-channel at the point of the pen,thereby allowing the ink and air to dow in opposite directions, the inkiiowing down along that side of the channel marked m on any pressurewhich bends the pen away from contact with the point e, while air risesthrough the small perforation H at the opposite side of the tube, thuspreventing stoppage of the ilow by vac- 1111111.

Vhere the air-hole H has heretofore been used it has been foundnecessary to produce the feed by compressing with the thumb andV fingersan elastic chamber, through which the ink flows, but this is notnecessary, and feed may be effected more perfectly and without thetrouble of any extra pressure by simply making the belly of thefeed-tube larger at m and maintaining or slightly increasing the bore ofthe tube E upward, as shown in Fig. l, so that the proportion betweenthe area of the same at and above the air-hole H will be to that of thenarrowest part of the feed G about as stated.

When not in use, the pen and feed-tube are covered by the cap I, fittingtightly upon the outside of the nipple a in the usual manner.

A little higher up from the point IOO In conclusion, I acknowledge theUnited States Patents Nos. 145,102, 18,365, and

222,959, and disclaim the construction shown in either of the saidpatents.

Having thus described my invention, I elai 1n as new and desire tosecure by Letters Patent- 1. In a fountain pen-holder, the combination,with the hollow stem A, having` the bottom chan nel, a, enlarged toreceive the feed-tube and pen, as set forth, of the tube E, fitted withits inner end tightly and with its outer end loosely into the saidenlargement, and the pen F, inserted between the said tube andenlargement, the said tube being of th e curved and graduallytaperingshape shown, and being also provided 4with the feed-channel G andair-hole H, and

having several times larger area of cross-seetion at and above theair-hole than across the narrowest part of the feed-channel, as and forthe purpose set forth.

2. In aiountainpen, the combination of the following elements: thehollow stem A, hav

ing the bottom channel, a, enlarged to receive the feed-tube and pen,the feed-tube and pen E F, fitted in the said enlargement, as described,the valve-rod D, provided at its lower end with the valve d, and havingat its upper end a threaded enlargement, c, and a knob, C, theperforated cap B, having an inside thread, b, to receive the thread c,and an outside thread, b, by which it is itted into the upper end of thestem A, and the packing S, fitted in the thread of the stem A, andsurrounding tightly the valve-rod I), all constructed substantially ashereinbefore set forth.

In testimony that I claim the foregoing as my invention, I have signedmy name,in presence of two witnesses, this 7th day of April, 1883.

JAMES MORTON.
